Abstract

　可変吸気機構の動作状態の検出結果の信頼性が低下している場合でも、実際の吸入空気量に応じて、空燃比制御および点火時期制御を適切に行うことができる内燃機関の制御装置。空燃比および点火時期を制御する制御装置１は、ＥＣＵ２を備える。ＥＣＵ２は、目標空燃比KCMDを算出し(ステップ22)、空燃比をフィードバック制御するための空燃比補正係数KSTRを算出し(ステップ2～7)、空燃比指標値の統計処理値KAF_LSを算出し(ステップ82)、統計処理値KAF_LSに応じて、補正後バルブリフトLiftin_compおよび補正後カム位相Cain_compを算出し(ステップ81～92)、補正後バルブリフトLiftin_comp、補正後カム位相Cain_compおよび空燃比補正係数KSTRに応じて、燃料噴射量TOUTを決定する(ステップ20～25)。
